@stephenrobles.com have you experienced success with “Screen unknown callers”? I had to switch it off as it asked my wife for her reason for calling 😂. In fact it asked every caller despite many being in my contact list.

In my previous article, I wrote about the inherent incompatibility of Active Directory with modern enterprise security architectures and cloud strategies. Another design vulnerability was presented at BlackHat USA on 6th August 2025.

This story resonates with me. Technology companies don’t communicate with parents sufficiently about the options available protect their family in these situations. That said, as a parent, I find it strange that it took them so long to even notice this, especially as their daughter is 8 years old.
